    • An adhesive is applied to a male-threaded portion of a tapping screw. The male-threaded portion with the adhesive is threadably engaged with a non-threaded through hole of the full-closed stopper with female-threads being formed on the surface of the though hole. In this case, the adhesive functions as lubricant between the inner surface of the through hole and the male-threaded portion. Accordingly, the male-threaded portion can be screwed into the through hole with a low torque and without applying high load to the full-close stopper. Therefore, the full-close stopper is prevented from being projected around the inlet and the outlet of the through hole, and the full-close stopper is prevented from being cracked.
    • 将粘合剂施加到自攻螺钉的阳螺纹部分。 具有粘合剂的阳螺纹部分与全闭塞的非螺纹通孔螺纹接合,阴螺纹形成在通孔的表面上。 在这种情况下,粘合剂在通孔的内表面和阳螺纹部分之间起润滑剂的作用。 因此,外螺纹部分可以以低扭矩拧入通孔,而不对全闭塞施加高负载。 因此,能够防止全关闭止动件在通孔的入口和出口附近突出,并且防止全关闭止动件破裂。

    • A light-controlled light modulator can achieve high-speed, low-loss wavelength conversion. Continuous light with a wavelength λj is launched into an MMI coupler via a port, and is split into two parts by the MMI coupler, which are led to a loop-type interferometer. In the loop-type interferometer, the two parts travel separately around the loop as clockwise traveling light and counterclockwise traveling light, are combined by the MMI coupler again via a filter-equipped phase modulator, thereby being emitted to the port. In this state, signal light λi(s) with a wavelength λi is launched into the filter-equipped phase modulator via a port. Even when the wavelength λi of the signal light λi(s) is equal to the wavelength λj of the wavelength converted output light, the wavelength conversion can be achieved with preventing noise from being mixed into the output light emitted from a port.
    • 光控光调制器可以实现高速,低损耗的波长转换。 具有波长lambdaj的连续光通过端口发射到MMI耦合器中,并由MMI耦合器分为两部分,其被引导到环型干涉仪。 在循环式干涉仪中,两个部件围绕环路分别作为顺时针行进光和逆时针方向的行进光,通过MMI耦合器再次通过配有滤波器的相位调制器组合,从而被发射到端口。 在这种状态下,具有波长lambdai的信号灯lambdai通过端口发射到装有滤波器的相位调制器中。 即使当信号光的波长长度等于波长转换的输出光的波长lambdaj时,也可以通过防止噪声混入从端口发出的输出光中来实现波长转换。

    • The reference position is determined, by using a test piece, for optically detecting the orientation of a component such as a chip for use in placement apparatus such as a chip mounter. Light is emitted from a light source toward a light sensor to cast a shadow of the test piece onto the light sensor. A first position of an end of the shadow when the pick-up device rotates at a first angle, a second position of the other end of the shadow when the pick-up device rotates at a second angle, and a third position of either end of the shadow when the pick-up device rotates at a predetermined third angle, are detected on the light sensor. Accordingly, the positional relationship of the light source, the light sensor, and the pick-up device is determined as a reference position, based on the positional data.
    • 通过使用测试件来确定参考位置,以光学检测诸如芯片安装机等放置装置中的芯片等元件的取向。 光从光源向光传感器发射,将试片的阴影投射到光传感器上。 当拾取装置以第一角度旋转时阴影结束的第一位置,当拾取装置以第二角度旋转时阴影的另一端的第二位置,以及任一端的第三位置 在光传感器上检测到拾取装置以预定的第三角度旋转时的阴影。 因此,基于位置数据,确定光源,光传感器和拾取装置的位置关系作为基准位置。
